9 Claims.

This invention relates to paper delivering devices particularly adapted to deliver paper to printing presses and the like, and has for its object to provide a new and improved device of this description.

In the operation of printing presses at the present day, the paper for the newspapers is wound into rolls and these rolls are supported in.

proximity to the press and the paper delivered to the press and formed into the newspapers. The presentpresses are run at a very high speed and it has been heretofore necessary to slow down the presses when the delivery of the paper to the press was changed from one roll to another. One object of the present invention is to provide means for preventing this and for permitting the transfer of the delivery of the paper fromone roll to another While the press is running at high speed The invention has further objects which are more particularly pointed out in the accompanying description.

Referring now to the drawings, wherein I have shown one form of construction embodying the invention, there is illustrated a roll supporting device for supporting the rolls of paper, which in 1932. Serial No. 587,050

this instance is indicated as a reel having the arms 1 between which the rolls of paper 2, 3 and 4 are received. Any suitable means is provided for rotating these arms to bring the new roll into proper position. As herein shown the arms are connected with a shaft 5 which is driven by a motor 6 through a gear 7. The shaft is mounted upon the pedestals 8 or it may be supported in any desired manner. In proximity to the rolls of paper are a series of belts 9 spaced apart. Each ofthese belts passes around a series of direction changing devices. In the particular construction shown each belt passes around the direction changing devices 10, 11, 12, 13 and 14. The direction changing devices 10 and 11 are located above the roll supporting device, and the direction changing devices 13 and 14 are preferably connected with the floor, one of them being preferably below or in proximity to the bottom of the roll support. The direction changing device 12 for each belt is arranged in some manner to keep the belt taut. In the particular construction shown this direction changing device is illustrated as a pulley rotatably mounted in a carrier 15, slidably mounted on rods 16 which are suitably supported in position as by being connected to the supports 1'7 and 18. These supports 17 and 18 are supported in any desired manner as by means of the brackets 19. These carriers 15 are weighted and are made sufliciently heavy to move the direction changing devices 12 as the roll of paper decreases in size so as to lreep the belts taut and in proper contact with the roll of paper. The web of the new roll 3 is provided with an adhesive 20 for the purpose of connecting it with the web of the expiring roll. A pressure device 21 is located in proper position to press the web of the expiring roll against the web of the new roll with sufficient pressure to cause the portion of the web of the new roll with adhesive thereon to adhere to the web 22 of the expiring roll. This pressure device 21 may be of any suitable form. For purposes of illustration I have shown it as consisting of a roller mounted in bearings 23 which are slidably mounted in guides 24, the bearings preferably being provided with springs 25 and 26 normally pressing it toward the roll 3. An adjusting device 27 is associated with these bearings so as to control their position and hence the position of the roller and the pressure it applies.

The belts 9, as herein shown, are driven at the desired speed and the portion of the belts which contact with the roll of paper are moving downwardly. The adhesive 20 is placed between the belts 9 so that these belts will not engage it.v When the expiring roll is about exhausted it is moved away from the belt so that the web 22 engages the pressure device 21 and the new roll 3 is moved into contact with the belts and brought 'up to the desired speed, and when at the desired "speed the new roll 3 is moved into contact with the web running over the pressure device 21, and then as the adhesive 20 comes around it will engage the web 22-of the expiring roll, thereby connecting the web of the new roll with the web of the expiring roll. When the belts 9 are run at the same speed as the press, or at a speed only slightly difiering from that of the press, it will be seen that the roll of paper 3 is brought into sub. stantially the same speed as the web 22 being delivered to the press, and that this flying paster or, connection between the web of the expiring roll and the web of 'the new roll maybe made while the press is running at full speed.

In delivering paper to printing presses, for example, it is desirable under certain conditions to drive the belts 9 at a speed somewhat slower than the speed of the press so that the belts will have a retarding effect on the roll to insure the tautness of the paperbeing delivered to the press. In cases where the difference in the speed of the belts and the speed of the press is such that there might be a slip between the web of the expiring roll and the adhesive on the web of the new roll when. the connection is being made, I provide means for compensating for this. Under'suhhconditi'ons may, for example, speed up the bltsQ-Just before the adhesive 20 on the new roll is brought into contact with the web of the expiring'roll so as to bring the two webs at substantially-,the same speed, at the time the connectio is made. In. the drawings I have shown onemeans for this purpose. I may, for example, arrange the direction changing devices 10 and 11 so that one of, them is larger in diameter than the'other. For example, the direction changing device 10 may be made large in diameter than the direction changing device 11. Imay then provide means for driving the belts normally through the smaller direction changing device 11, the connection to the driving mechanism being such that the belts will then be driven at the desired speed less than the speed of the press.

When it is desired to make the connection be- .tween the web of the expiring rolland the web of the new roll, the drive is changed to the direction changing devic'elo, and since this is larger v proper speed before the connection is made.

In the drawings I have shown a driving shaft 28, which may be a shaft on the press or may derive its power from any other source. This shaft has a driving connection 29 with a shaft 30. The shaft 30 is provided with the beveled gears 31 and 32. The beveled gear 31 engages the beva with so as to rotate with the shaft. The gear 32 is connected with the gear 3'7 which rotates freely on the shaft 38 but which has the clutch member 39 adapted to be engaged by the cluch member 40 slidable on the shaft 38 but rotating therewith.

The clutch members 39 and 40 are controlled by the controlling member 41 pivoted at 42. This 1 member maybe controlled by hand if desired,

or by any other means. As herein shown I have provided electrical means for moving the controlling member. An electromagnetic device 43 is provided with an armature or core 44 connected with the controlling device 41 so as to actuate it. A retracting spring 45 is also connected with the controlling device. The electromagnetic device 43 is connected by the conductors 46 withthe electric circuit 47 through a switch 48. When the switch is moved to its closed position, current passesthrough the electromagnetic device and moves the controlling element 41 to disconnect the clutch element 36 with the clutch element 35, and connect the clutch element 40 with the clutch element 39, thereby changing the drive from the direction changing device 11 to the direction changing device 10. (See Fig. 6.) Since the direction changing device 10 is larger in diameter than the direction changing device 11, it will be seen that the belts, with the same speed as the shaft 30, will then be speeded up and the parts are so arranged and adjusted to secure the desired speed. When the roll 3 has been brought to the desired speed and the paster made, the switch 48 is opened and the spring 45 moves the controlling element 41 so as to again connect the shaft 30 with the direction changing device 11.

The apparatus is normally run when the parts are in this condition. It is of course evident that this speed changing device is only used under conditions where it is necessary and may be omitted when the difference in speed of the belts 9 and the press is not such as to require it to make a proper paster or connection between the expiring roll and the new roll.

I have shown in Fig. '7 a detail of one of the beveled gears, showing an arrangement whereby the gear 3'7 may rotate freely on the shaft 38. In this construction the end of the gear is recessed and a plate 49 is attached tothe end of the shaft by a fastening device 50 which prevents the gear from coming off of the end of the shaft. The other end of the gear is recessed and a collar 51 in this recess is connected with the shaft 38 by the fastening device 52. I It will thus be seen that the gear can rotate freely on the shaft, and when the clutch member 40 is connected with the clutch member 39, the gear is connected,with the shaft 38 so as to rotate it. The other gear 33 is similarly arranged. 1'

I have shown diagrammatically a severing device 53 for severing the web from the expiring roll after it has been connected with the web of the new roll.

The use and operation of my invention are as follows:

When the device is in use the rolls of paper are placed upon the roll or support, and one of these rolls, as for example the roll 2, is moved is shown in Fig. 8.

When the roll 2 is nearly exhausted the roll supporting device is moved so as to bring the roll3 into contact withthe belts 9, as shown in Fig. 9. This also brings the web 22 of the expiring roll into contact with the pressure device 21 and the parts are in the position shown in 'Fig. 9. The contact of the belts 9 with the roll 3 of paper causes said roll to be set in motion and it is rotated in the direction of the arrow until it attains the proper speed. The roll support is then moved further to bring the roll 3 into contact with the web 22 and press it against the web of the new roll so as to connect the web of the new roll with the web of the old roll and change the feed to the web of the new roll 3. This position is-shown in Fig. 10. The web 22 is then severed and the paper is delivered to the press from the new roll 3, all of this being done while the press is running at its high speed and without slowing it down. I have shown diagrammatically in Fig. 11 a severing device 53 for severing the web 22 of the expiring roll.

II the difierence in speed of the belts 9 and the web of paper being delivered to the press is sufliciently great to make it diflicult or impossible to make the connection between the web of the expiring roll and the web of the new roll, when the new roll is brought up to the high speed the belt will give it, then when it is desired to change the feed from one roll to the other, the belt 9 is speeded up by energizing the electromagnetic device 43 by closing the switch 48. This changes the drive from the shaft 34 to the shaft 38 and direction changing device 10. The belt is then speeded up to the desired speed and this causes the new roll 3 to be rotated at the desired speed so that when it is brought into contact with the web 22 of the expiring roll, the end of the web on the new roll having adhesive will be pressed against the expiring web 22 by the pressure device 21 and the two webs connected together.- It will be seen that by means of this device the web of the new roll may be connected to the web of the expiring roll while the press is running at its full speed. It will further be seen that as one roll of paper runs out so as to be nearly exhausted, the next roll is then brought into action in the same manner as above described. A new roll is put in the place of the expired roll and the process is continued as long as desired so that it is unnecessary to' stop the press or slow it down for the purpose of changing the feed from one roll to another.
